My camera will power up on display mode and I can view pictures. When I try to power up the camera in shoot mode to take pictures the display say's "Change Batteries". I have tried many new batteries with the same result. This happened in a very high humidity area of Mexico.

Re: Canon PowerShot A85
I decided to send you this from the Canon website to see if this helps:
Issue: What are the specifications for batteries that I can use in my camera? Solution: Recommended AA batteries for your camera.
What types of AA batteries can I use?
Canon rechargeable (NiMH) batteries
For the best results, we recommend using Canon rechargeable (NiMH) batteries. Rechargeable batteries provide the best performance and are the most economical choice. The Canon Battery & Charger Kit includes a battery charger and four rechargeable AA-size NiMH (nickel metal hydride) batteries. The battery kit can be purchase from the Canon eStore. AA alkaline batteriesAA alkaline batteries such as those from Energizer or Duracell will provide the best performance for non-rechargeable batteries.
ALL AA-based PowerShot digital cameras (including A Series and S5 IS / SX100 IS-type):"Never use manganese (non-alkaline) batteries."
Since the performance of alkaline batteries may differ according to brand, the operating time of the batteries you purchase may not be as long as the batteries that came with the camera.
Camera operating time may shorten at low temperatures when alkaline batteries are used. Also due to their specifications, alkaline batteries may expire faster than NiMH batteries. If you are using the camera in cold areas or for a long time, we recommend using Canon AA-size NiMH Battery Kit (a four piece set).
While it is possible to use AA-size nickel-cadmium rechargeable batteries, performance is unreliable and their use is not recommended.
Never mix unused and partially used batteries. Always load two or four (depending on camera model) fresh (or fully recharged) batteries at the same time.
Be careful to load the batteries with their positive (+) and negative (-) ends in the right direction.
Never mix batteries of different types or from different manufacturers. All batteries should be identical.
Before inserting the batteries, wipe the battery terminals well with a dry cloth. Oil from ones skin or other dirt may cause a considerable reduction in the number of recordable images or reduced usage time.
Battery performance deteriorates at low temperatures (especially with alkaline batteries). If you are using the camera in cold areas and batteries are running down faster than they should, you may be able to restore performance by placing batteries in an inner pocket to warm them up prior to use. But be careful that you don't put the batteries into a pocket together with a metal key chain or other metallic objects, as these objects may cause batteries to short-circuit.
If you do not plan to use the camera for a long time, remove the batteries from the camera and store them in a safe place. Batteries may leak and damage the camera if left installed during prolonged periods of non-use.
WARNING Never use damaged batteries or batteries whose outer seal is completely or partially missing or peeled off, as there is risk that such batteries may leak, overheat, or burst. Always check the seals on store-bought batteries before loading them, as some batteries may come with defective seals. Do not use batteries with defective seals.

Hi Toonz I have exactly the same problem as Shimoni and Antonio with my 4 years old A85. But sorry, its not a problem of the CCD, cause we all get a clear actual picture on the LCD but just in stitch mode! In any other shooting or playback mode the LCD is dark. So the sensor must be working well and Canon Germany doesnt repair for free. Our failure is different and we have to pay much more than the camera is worth ;-(( Dieter, Munich
Has this just happened or has it always been like this?
There appears to be a a fault in the main board and only replacement will cure-
So may be if the camera is more than a year or so old- time for a new one.
Meanwhile do speak to the Canon Tech Support on the Web site.
And whilst the matter is still not resolved ,shoot holding the camera upside down- seriously - tell me what happens.
